Quantum Mechanic

Quantum Mechanic

1. What is this?

   • Is the branch of physics relating to the very small.
   • In classical mechanics, objects exist in a specific place at a specific time.

2. Quantized properties

   • Certain attributes, such as position, speed, and color, can sometimes only appear in a specific, set amount, just like a dial "clicks" from one digit to another.

3. Waves of matter

   • In 1927, Walter Heitler and Fritz London further developed wave mechanics to show how atomic orbitals could combine to form molecular orbitals, effectively showing why atoms bond to one another to form molecules. Matter can also behave as a wave.

4. Particles of light

   • Light behaves similarly in that it bounces off walls and bends around corners, and that the crests and troughs of the wave can add up or cancel out.

5. The Uncertainty principle

   • He reasoned that since matter acts as waves, some properties, such as an electron's position and speed, are "complementary," meaning there's a limit (related to Planck's constant) to how well the precision of each property can be known.
